Self-regulating valve without additional energy, the use of the media itself as the power source, the introduction of the actuator control spool position, change the pressure and flow at both ends of the bend, so that the valve before (or valve) pressure stability. Germany Hank (HANK) self-regulating valve with action sensitive, good sealing, pressure set point wave power is small, widely used in gas, liquid and steam medium pressure regulator or pressure regulator automatic control.
1, the direct role of regulating valve
Also known as the spring-loaded control valve, the structure of the elastic components: such as springs, bellows, bellows-style package, the use of elastic force and feedback signal balance principle.
2, indirect acting control valve
Added a pilot (pilot valve) which acts to amplify the feedback signal and then through the actuator to drive the main valve flap to achieve the purpose of changing the valve opening.
If the pressure regulating valve, the feedback signal is the valve outlet pressure, through the signal tube into the implementing agencies.
In the case of a flow control valve, there is an orifice plate (or other resistance means) at the outlet of the valve which is introduced into the actuator by removing the differential pressure signal from both ends of the orifice plate.
If it is a temperature control valve, the valve outlet has a temperature sensor (or temperature package) through the temperature sensor medium thermal expansion and contraction drive actuator.
1, the valve in the gas or low viscosity liquid medium used, usually self-regulating valve for the vertical installation of the horizontal tube, when the location space is not allowed when the flip or ramp loading.
2, in order to facilitate on-site maintenance and operation, pressure regulator should be left around the appropriate space.
3, when the medium is clean gas or liquid, the valve before the filter may not be installed.
4, the regulator valve diameter is too large (DN ≥ 100 hours), should have a fixed bracket.
5, the position is not allowed, the bypass valve (manual) can be omitted (we do not recommend).
6, after the valve group according to the needs of users optional check valve, safety valve.
7, the valve in the steam or high viscosity liquid medium, usually self-regulating valve for inverted installation in the horizontal tube, the condenser (steam with self-type) should be higher than the regulator valve actuator and lower than the valve before and after the tube The Before use the condenser should be filled with cold water, after about 3 months irrigation time.
成立于1852年创建于门兴格拉德巴赫（Monchengladbach）是位于德国北莱茵-威斯特法伦州首府杜塞尔多夫市以西的一座城市。于19世纪50年代初德国经济快速发展，由于德国能源短缺，政府在节能方面加大力度，因此HANK(Trouble Less valve没有故障的阀门)公司成立。汉克阀门是以生产高品质、先进的阀门、测量及控制系统而享誉全球的跨国性生产企业，在全球几十个国家拥有子公司及分支机构，公司产品涉及用途：石油、化工、电力、冶金、制药、食品、水处理、市政给排水、天然气、造纸、电子工业、楼宇、机械设备配套等领域。
GERMANY HANK VALVE LIMITED is founded on 1852 in Monchengladbach,which is located at one city in North Rhine in Germany, which is the west of Nordrhein-Westfalen. At the beginning of 1850s, as the rapid development of economic and the shortages of energy in Germany , the government had been in saving energy aspect. On this occasion, HANK Valve (Trouble Less Valve) was established.Hank valve is the world-famous transnational production enterprise,which produces high quality and advanced valve, measurement and control system, and which has its divisions and branches in dozens of countries in the global. The company products user involves the petroleum, the chemical industry, the electric power, the metallurgy, the drugs manufacture, food, the water treatment, the municipal administration to give draining water, the natural gas, the papermaking, the electronics industry, the building, the mechanical device necessary ect..
The conclusion of the valve concept in German Hank valve is resposibility,foresight,innovation. For ourselves resposibility, foresight and focusing on creating unprecendented solution and concept,our company has become the lead of valve manufacturer in the global.标签:   自力式调节阀 进口自力式调节阀
